  • 4e34e719e   fs: take the ACL checks to common code ... Browse Code »

    Replace the ->check_acl method with a ->get_acl method that simply reads an
    ACL from disk after having a cache miss. This means we can replace the ACL
    checking boilerplate code with a single implementation in namei.c.

  • 2a7dba391   fs/vfs/security: pass last path component to LSM on inode creation ... Browse Code »

    SELinux would like to implement a new labeling behavior of newly created
    inodes. We currently label new inodes based on the parent and the creating
    process. This new behavior would also take into account the name of the
    new object when deciding the new label. This is not the (supposed) full path,
    just the last component of the path.

    This is very useful because creating /etc/shadow is different than creating
    /etc/passwd but the kernel hooks are unable to differentiate these
    operations. We currently require that userspace realize it is doing some
    difficult operation like that and than userspace jumps through SELinux hoops
    to get things set up correctly. This patch does not implement new
    behavior, that is obviously contained in a seperate SELinux patch, but it
    does pass the needed name down to the correct LSM hook. If no such name
    exists it is fine to pass NULL.

  • 590fe34c4   [JFFS2] Quiet lockdep false positive. ... Browse Code »

    Don't hold f->sem while calling into jffs2_do_create(). It makes lockdep
    unhappy, and we don't really need it -- the _reason_ it's a false
    positive is because nobody else can see this inode yet and so nobody
    will be trying to lock it anyway.

  • 5451f79f5   iget: stop JFFS2 from using iget() and read_inode() ... Browse Code »

    Stop the JFFS2 filesystem from using iget() and read_inode(). Replace
    jffs2_read_inode() with jffs2_iget(), and call that instead of iget().
    jffs2_iget() then uses iget_locked() directly and returns a proper error code
    instead of an inode in the event of an error.

    jffs2_do_fill_super() returns any error incurred when getting the root inode
    instead of EINVAL.

  • cfc8dc6f6   [JFFS2] Tidy up fix for ACL/permissions problem. ... Browse Code »

    [In commit 9ed437c50d89eabae763dd422579f73fdebf288d we fixed a problem
    with standard permissions on newly-created inodes, when POSIX ACLs are
    enabled. This cleans it up...]

    The attached patch separate jffs2_init_acl() into two parts.

    The one is jffs2_init_acl_pre() called from jffs2_new_inode().
    It compute ACL oriented inode->i_mode bits, and allocate in-memory ACL
    objects associated with the new inode just before when inode meta
    infomation is written to the medium.

    The other is jffs2_init_acl_post() called from jffs2_symlink(),
    jffs2_mkdir(), jffs2_mknod() and jffs2_do_create().
    It actually writes in-memory ACL objects into the medium next to
    the success of writing meta-information.

    In the current implementation, we have to write a same inode meta
    infomation twice when inode->i_mode is updated by the default ACL.
    However, we can avoid the behavior by putting an updated i_mode
    before it is written at first, as jffs2_init_acl_pre() doing.

    When POSIX ACL support was enabled, we weren't writing correct
    legacy modes to the medium on inode creation, or when the ACL was set.
    This meant that the permissions would be incorrect after the file system

    In particular, remove the bit in the LICENCE file about contacting

    that arrangement a long time ago -- the policy of collecting copyright

    the servers hosting the project, without notice or reason.

    We do still dual-license it for use with eCos, with the GPL+exception
    licence approved by the FSF as being GPL-compatible. It's just that nobody
    has the right to license it differently.

  • cd354f1ae   [PATCH] remove many unneeded #includes of sched.h ... Browse Code »

    After Al Viro (finally) succeeded in removing the sched.h #include in module.h
    recently, it makes sense again to remove other superfluous sched.h includes.
    There are quite a lot of files which include it but don't actually need
    anything defined in there. Presumably these includes were once needed for
    macros that used to live in sched.h, but moved to other header files in the
    course of cleaning it up.

    To ease the pain, this time I did not fiddle with any header files and only
    removed #includes from .c-files, which tend to cause less trouble.

    Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
    arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
    allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
    configs in arch/arm/configs on arm. I also checked that no new warnings were
    introduced by the patch (actually, some warnings are removed that were emitted
    by unnecessarily included header files).

    Many struct inode_operations in the kernel can be "const". Marking them const
    moves these to the .rodata section, which avoids false sharing with potential
    dirty data. In addition it'll catch accidental writes at compile time to
    these shared resources.

  • 9a53c3a78   [PATCH] r/o bind mounts: unlink: monitor i_nlink ... Browse Code »

    When a filesystem decrements i_nlink to zero, it means that a write must be
    performed in order to drop the inode from the filesystem.

    We're shortly going to have keep filesystems from being remounted r/o between
    the time that this i_nlink decrement and that write occurs.

    So, add a little helper function to do the decrements. We'll tie into it in a
    bit to note when i_nlink hits zero.
